I had originally added my site: http://www.muralsandfauxpainting.com
but later my hosting company told me to drop the www. in front of the
url.  I noticed that on webmaster tools, both http://www.muralsandfauxpainting.com
and http://muralsandfauxpainting.com are listed.  One notes that I
need to add a sitemap.  I don't want to get into any trouble.  Should
I add the site map to the url without the www. or should I delete the
other site?  I noticed that both sites are crawled but at different
times.  Please let me know what to do. Does everyone who types the www.
before any url get redirected to the url without the www. these days?
Also, I asked someone to look into my images alt. text to see how come
they are not being indexed, yet the pics that are just graphics (like
red arrows) are indexed and they don't have alt. text on them.  Thanks
for your help.  I used to be on the first page and ever since I made
some changes to content and adding h1 tags and alt. text, I have been
on the second page at the bottom.

God bless,
Sandy
